Abstract

This paper describes a research work to develop a computer-aided design of a product with bending and piercing operations for progressive working. The approach to the system is based on knowledge-based rules. Knowledge for the system is formulated from plasticity theories, experimental results and the empirical knowledge of experts in the field. The system has been written in AutoLISP with AutoCAD on a personal computer and is composed of three main modules: input and shape treatment, flat pattern layout, and strip layout modules. The system is designed by considering several factors, such as piercing and bending sequence by fuzzy set theory, complexities of blank geometry, punch profiles, and the availability of press equipment. The strip layout module generates the 3D strip layout drawing with the punch profiles for the external area of a product according to the results of the FVM set. The system could serve as a valuable system for experts and as a dependable training aid for beginners.
